RAINBOW DASH: "I look like I have a mohawk blowing in the wind, don't I? Yeah, I think I just got about 20% cooler."
FLUTTERSHY [off-screen]: "What? But, um... I thought you said it was lazy and uninspired to just quote fan-loved moments for these intros..."

DISCORD: “We really need to fire whoever named this two-parter, don’t we?”
SPIKE: “You’re annoyed about that? What about the rest of us? You and Twilight are the only ones in this shot with any substantial non-disposable dialogue this episode!”

APPLE BLOOM: "You know, I was being forced to do so much stuff with all them there cutie marks, that I couldn't even see half of them! There's a mallet, a fancy brush, two thin swords hitting each other... Man, am I glad I have just the one cutie mark now!"

TWILIGHT: "Okay - why am I wearing a bowler hat?"
PINKIE: "Perfect silly question, my dear Twilight. Because the obvious answer is..."
APPLEJACK: "...there is no answer, is there, sugarcube?"

SPIKE: "Oh yeah, I remember this! The time when I went from just another sidekick to a hero in my own right. And it showed all those naysayers you weren't a token princess either, Cadence!"
CADENCE: "Wait - who was saying I was just a token Princess?"
SPIKE: "Uh... the Shadowbolts?"

TWILIGHT: "You see, Princess Luna? If you just show other ponies the real you, they'll learn to love you all the same!"
LUNA: "If you say so, Twilight Sparkle. And perhaps then we might enjoy the same level of popularity that you generate amongst your fans?"
TWILIGHT: "Huh? Luna, haven't you been on the internet?"

KING SOMBRA: "Crystals..."
[clears throat] "Wow, small wonder I became something of a joke in the fandom, if that was all I got to say for nearly six seasons."

SPIKE: "That Angel Bunny. Up to no good as usual! And here I thought Discord caused chaos."
DISCORD: "You rang? Oh, all these pets sow plenty of chaos, you know. Why, I should stick around to see it -"
SPIKE: No, Discord. We're not doing that."

TWILIGHT: "Hm. Feels like this would be a good point to insert a meta-joke about how I look very much like my future Princess self in this shot, with the glowing heavenly/demon eyes and everything. Here we go -"
APPLEJACK: "No, Twilight, no we're not doing that, sugarcube."
